PROCESS OF MAKING WASHING-CREAM AND PRODUCT OF THE SAME.

1,180,279. 80 Drawing.

To all'wkom it may concern Be it known that I, CHARLES BAnoEEN, a citizen of the United States, residing at Schenectady, in the county of Schenectady.

and State of New York, have invented a new and useful Process of Making Washing Cream and Product of the Same, of which the following is a specification.

This invention relates to a washing cream and more especially to a method of preparing the same. I

While the value of coal oil has long been recognized by manufacturers of cleansing preparations, it has not heretofore been pos= sible to malntaln for any cons1derable period a mixture of coal oil and other cleansing ingredients and for this reason the production of a cleansing preparation containing coal oil has not heretofore been successful.

One of the objects of the present invention is to provide a Washing cream utilizing coal oil as an ingredient, the same being con stantly held under suspension in the mixture so that no change in the appearance or other characteristics of the compound will take place after the mixture has once been effected. V

In preparing the washing cream, the following steps are followed :First, a resinous soap is made by melting together and mixing thoroughly linseed oil and rosin in the proportions of 100 pounds of linseed oil to pounds of rosin and after this mixture has'been made the same is saponified by adding thereto lye made up of pearl ash and soda ash each dissolved to 78 test. Second, two pounds of resinous soap produced as above described are placed in 2 gallons of water and the water is brought to a boil so as to melt the soap and effect a thorough mixture of the soap and water. To this mixture coal oil is gradually added during the boiling operation until 8% gallons of coal oil have been used. The additionpf thecoal oil produces a thick oily white cream. It might be stated that should the preparation of the washing cream stop at this point, the mixture would separate into a thick heavy cream, water, and coal oil which would lie in three distinct layers in the container. Furthermore the use of such a mixture While resulting in the thorough cleansing of fabrics, would cause the fabrics to turn yellow by reason of the coal oil contained in the mixture. In order to avoid the foregoing objections, a further Specification of Letters Patent. Patented Apr, 25,1916. Application filed July 20, 1915. Serial li o. 40,907.

step is involved in the preparation of the washing cream constituting thi'sinvention. This third step consists in the mixin of 1% pounds of oil of citronella and iga lon of coal oil which mixture is permitted to stand for twenty-four hours, thus to break up the citronella and cause a thorough commingling of the two ingredients of the mixture. After this mixture of coal oil and oil of citronella has been allowed to stand for the period stated, it is thoroughly agitated. It is then added to the thick oily cream made up of 2 pounds of resinous soap, 2 gallons of water and 8% gallons of coal oil. It has been found that by thus adding this mixture of coal oil and citronella, the thick cream, water and coal oil obtained upon the completion of the second step enumerated, will be set or, in other words, will be prevented from separating with the result that an oily emulsion will be produced, the same consisting of the resinous soap holding in suspension coal oil and oil of citronella. This ultimate mixture will remain indefinitely in the form of a cream or paste and will mix readily with water so that it thus becomes possible to use A the mixture for laundry and like purposes.

It is believed that only by following the process herein outlined can the several ingredients constituting the washing cream melting approximately two pounds of resinous soap in about 2 gallons of boiling water and thoroughly mixing the same, then adding about 8% gallons of coal oil to the boiling mixture to produce a thick oily white cream, and then preventing separation of the ingredients and producing an oily emulsion by adding to said cream a thoroughly agitated mixture of approximately L1- pounds of oil of citronella and gallon of coal oil.

2. The herein described method of producing a washing cream, which consists in melting together linseed oil and rosin, adding thereto a lye made of pearl ash and soda ash to produce a soap, dissolving approximately 2 pounds of the soap in about 2 galpounds of oil of citronella and '1 gallon of coal oil and permitting the same to stand to effect the breaking up of the citronella, then agitating said mixture of citronella and coal 5 011 and adding it to the cream to prevent se aration of the ingredients and produce an oi y emulsion holding coal oil and oil of citronella in suspension.

3. A washing cream for use with laun 10 soap, consisting approximately of 2 poun of resinous soap, 9 gallons of coal oil, 2 gallons of water, and 1} pounds of oil of citIronella. f

n testimony that I claim the oregoing as my own, I have hereto aflixed my slgnature in the presence of two witnesses.
